SunPower® Performance solar panels wrap front contact cells with SunPower's trusted quality and durability, resulting in a panel that offers superior efficiency, power, yield and reliability compared to Conventional Panels.*

  • *. Definition of “Conventional Panel” is a 310W panel, 16% efficient, approx. 1.94 m2, made with Conventional Cells. Conventional Cells are silicon cells that have many thin metal lines on the front and interconnect ribbons soldered along the front and back.

Engineered for reliability

An innovative shingled design eliminates many of the reliability challenges of traditional front contact panels. Fragile ribbons and solder bonds are removed to expand the active cell area, flexible and redundant connections keep energy flowing, and lower peak cell temperatures enable longer panel life.


Top performer in independent testing

In the 2018 DNV GL PV Module Reliability Scorecard, SunPower Performance panels were named as a top performer in all five reliability tests conducted: thermal cycling, damp heat, humidity-freeze, dynamic mechanical load and potential induced degradation.



Maximized energy production











SunPower® Performance panels offer 19.6% panel efficiency and up to 32% more energy over the first 25 years of operation when compared to Conventional Panels.*Performance panels also benefit from a unique parallel circuit design that delivers more energy in row-to-row shading, enabling greater ground or roof coverage.

Frequently Asked Questions

How do SunPower® Performance panels differ from conventional front contact panels?

SunPower Performance panels differ from Conventional Panels in a variety of ways. First, we laser cut each SunPower Performance cell into six strips and layer them in a shingled configuration to create a ‘hypercell’. This shingled hypercell allows us to fit more active cell area into each panel, boosting power and efficiency. Second, the performance series cells are connected with a conductive adhesive borrowed from the aerospace industry to offer multiple and redundant paths for electricity flow. This allows us to remove the front contact ribbons and solder bonds found in conventional cells that can block active cell area and deteriorate over time, leading to cell failures and power deficits. Finally, SunPower Performance panels feature a unique parallel circuit architecture that significantly limits power loss in shade and soiling. The result is a superior shingled panel constructed with commodity cells, outperforming conventional panels in efficiency, performance and reliability.

How does a SunPower Performance panel differ from SunPower® Maxeon® cell-based panel technology?

SunPower® Performance panels use front contact crystalline cells, as opposed to the Maxeon cell-based technology used in SunPower® E-Series and X-Series panels.

What is the typical performance advantage gained from using SunPower Performance panels in my installation?

We built the Performance panels for high reliability, maximum efficiency and lower degradation—driving an estimated 28% higher energy yield in a fixed space over the first 25 years of operation when compared to conventional panels.*

What is the typical cost advantage of using SunPower Performance panels in my installation?

Costs vary from project to project. However, Performance panels generally have a price point that is competitive with Conventional Panels and below the cost of SunPower Maxeon cell-based panels. Additionally, Performance panels take advantage of many of the materials and processes used to produce nearly 25 million Maxeon panels, delivering the same trusted SunPower quality and reliability at a fraction of the cost.
